NAME
       rmmod — simple program to remove a module from the Linux Kernel

SYNOPSIS
       rmmod [-f]  [-w]  [-s]  [-v]  [modulename]

DESCRIPTION
       rmmod  is  a  trivial  program to remove a module from the kernel.  Most users will
       want to use modprobe(8) instead, with the -r option.


OPTIONS
       -v --verbose
                 Print messages about what the  program  is  doing.   Usually  rmmod  only
                 prints messages if something goes wrong.


       -f --force
                 This  option  can  be  extremely  dangerous: it has no effect unless CON-
                 FIG_MODULE_FORCE_UNLOAD was set when the kernel was compiled.  With  this
                 option,  you  can  remove  modules which are being used, or which are not
                 designed to be removed, or have been marked as unsafe (see lsmod(8)).


       -w --wait Normally, rmmod will refuse to unload modules which  are  in  use.   With
                 this  option, rmmod will isolate the module, and wait until the module is
                 no longer used.  Noone new will be able to use the module, but it’s up to
                 you  to  make  sure  the  current  users  eventually finish with it.  See
                 lsmod(8)) for information on usage counts.


       -s --syslog
                 Send errors to the syslog, instead of standard error.


       -V --version
                 Show version of program, and exit.  See below for  caveats  when  run  on
                 older kernels.


BACKWARDS COMPATIBILITY
       This version of rmmod is for kernels 2.5.48 and above.  If it detects a kernel with
       support for old-style modules (for which much of the work was done  in  userspace),
       it  will  attempt to run rmmod.old in its place, so it is completely transparent to
       the user.
